  Comment was about amateur radio (https://en.wikipedia.org/wiki/Amateur_radio https://en.wikipedia.org/wiki/Amateur_radio) and more particularly about contests (https://en.wikipedia.org/wiki/Contesting https://en.wikipedia.org/wiki/Contesting). The WebSDR receiver posted by the OP allows reception on 0-30 MHz range, which includes a number of amateur radio bands.
